Garland, Randall J., & Dougher Michael J.; The Abused/Abuser Hypothesis of Child Sexual Abuse: A Critical Review of Theory and Research; 488-509
A widespread belief among the general public and professionals alike is that “sexual abuse causes sexual abuse”. That is, sexually abused children and adolescents who have engaged in sexual behavior with an adult (or a significantly older adolescent) are commonly thought to be at risk in later years of themselves becoming sexually involved with children and adolescents. This belief is referred to here as the “abused/abuser hypothesis of child and adolescent sexual abuse.”
Given the popularity of the abused/abuser hypothesis, it is perhaps surprising to find that there is a dearth of evidence supporting it. This is not to say that there is a substantial body of contradictory evidence. Rather, only a handful of studies have actually investigated the presumed association, and the designs and methods of these studies have been less than ideal. Most of the relevant data come from retrospective studies of adults that do not allow for direct causal analysis.
"The conclusion that seems warranted from the review is that childhood and adolescent sexual contact with adults is neither a necessary nor a sufficient cause for becoming an adjudicated sex offender of children or adolescents."
"Thus, sexual contact with an adult during childhood or adolescence is not a necessary cause for becoming an adjudicated adult sex offender of children and adolescents. Sexual contact with an adult during childhood or adolescence also does not appear to be a sufficient cause for becoming an adjudicated sex offender of children and adolescents."
"In summary, the abused/abuser hypothesis — the belief that sexual behavior between adults and children or adolescents causes those children and adolescents, as adults, to become sexually involved with other children and adolescents — is inadequate and incorrect."
"The belief that sexual abuse causes sexual abuse, the so-called “abused/abuser hypothesis,” is simplistic and misleading."
"The conclusion reached is that sexual contact with an adult during childhood or adolescence is neither a necessary nor a sufficient cause of adult sexual interest in children or adolescents."
